SEAL- LOCK.

SPECIFICATION forming part Of Letters Patent No. 700,298, dated May 20, 1902.

Application filed May 24, 1901., Serial No. 61,759- (No model.)

To all whom it may cancer-m Be it known that I, PERRY BRowN, a citi zen of the United States, residing at Wilmington, in the county of Newcastle, State of Delaware, have inventeda certain new and useful Improvement in Seal-Locks,'ofwhich the following is a specificatiom reference being had to the accompanying drawings.

Thisinvention relates to an improvement in seal-locks of the class particularly adapted for use on freight-car doors; and my object is to produce a simple, inexpensive, and durable lock. which will be most effective in use and easily operated.

Having this object in view, my invention consists in the peculiar construction, arrangement, and combinations of par'ts'as described in its preferable embodiment in the following specification and then definitely set forth by the claims at the end hereof.

In theaccompanying drawings, illustrating my invention, Figurelis a side elevation of part of a car-door with myimprovements illustrated thereon. Fig.2is a similar view of the same with the pivoted hasp raised. Fig. 3 is a longitudinal central section. an inverted side elevation taken from the rear side and with parts removed. Fig. 5 is a longitudinal central sectionjthrough the lock on a somewhat larger scale, and Fig. 6 is a detail perspective view of the seal-holder with its pivoted cover raised.

Referring now to the details of the drawings by numbers, 1 indicates part of the cardoor, and 2 part of the car, the former having a hasp 3, pivoted thereto by means of the piv otal bolt on pin 4 and the latter having the usual or any form of catch or keeper 5, rigidly secured thereto. The pivoted hasp3has two integral ribs 6 and'7, forr ned1on'its exterior surface, each of which is arranged tofcoact with the catch orkeeper 5-"to"prevent'.the

door from opening, the rib 6 being used when it is desired toholdthe' door entirely'sh'ut" and the rib? when the freight beingshipped Fig. 4: is

mechanism for operating the-seal-mutilator. The said plate Sis provided with a'bossll, through which passes the pivotal bolt or pin 4, which thus performs the double function of securing the plate 8 in position and of acting as a pivot on which the hasp swings, as before described. 'lhishasphas a glass-proover the recess 9, containing the way-card when the hasp is in its locked position, as shown in Fig, 1, and a similar opening 13 to expose the seal. The hasp-3 alsohas chambers or recesses 14: and 15, which open downward and which contain the bolt 16 and the in place by the plate or coverlS. This bolt 16 is' arranged to be moved longitudinally ofits length in its recess 15, so as to move into an opening 19, formed within the chamber 10 said casing. The spring 17 for causing the locking movement of the boltlG is supported by a pin'or lug 21, and the inactive end of the clearly seen in Fig. 4.

It will be obvious from the scription and the accompanying drawings (see particularlyFigl 4) that when the hasp 3 is swung on its pivot 4 into the locking po-' sition (shown in Fig. 1) the bolt 16, projecting out'of its recess 15, will strike against the curved surface 23 (see Fig. 4) of the casing and be thereby caused to enter its recess 15,

face 23, when the spring 17 will shoot the bolt 1 into the'opening 19 of the casing, and therebylock-the has'pto said casing.

Tounlock'the hasp and at the same time operate: the" sealmutilator, l I provide the mechanism contained within the chamber 10, which may be described as "follows: A sliding-boltoperator 25 is located in. the opening recess 27, to limitlthe'inovement of the operator 25. Situated substantially at right an 1 gles to said operator is a sliding pusher 28, having teeth thereon forming a racke29, with I for the purpose of acting as a housing for the foregoing deso as to allow it to pass by said. curved sur- 6o tected sight-opening 12, arranged so as to be spring 17 for actuating it and which are held of the casing, and thereby lock the haspto spring isheld against a rib 22, all of which is 19 'andfis providedwi'th'ajlug 26, sliding in a which meshes a pinion30", preferably jour-' naled on trunnions 31 32, as shown in Fig. 5.. The upper trunnion 31 of this pinion 30 is projected through an opening inthe upper wall of the chamber, and on the other side of said wall is a recess 33, in which a circular seal-mutilator rotates, said seal-mutilatorbeing rigidly secured to said trunnion, as by riveting or otherwise. This seal-mutilator consists of a base 34, to which are rigidly connected the pointed knives 35, and the mutilator rotates within the aforesaid recess 33, formed by the annular rim 36, projecting, upwardly from the casing. The said casing also has a cover 37 hinged thereto,which coverhas an annular groove 38, so that the cover may fit down over the rim 36 and hold a seal 37 thereon, the cover having an opening 38 therein, through which the information on the seal may be read. On reference to Figs. 2 and 6 it will be observed that the knives 35, projecting from the seal-mutilator 34:, are arranged at different distances from the center of the seal-mutilator, so that as the seal-mutilator rotates the knives will more effectually eut and mutilate the seal which is held by the cover 37.

\Vhen the hasp is closed, as seen in Figs. 1 and at, it has a downwardly-projecting flange 39 formed thereon, (see said Fig. 4,) so that it will tightly fit the casing containing the seal and way-card, and thus prevent rain or moisture from entering between the hasp and casing.

The operation of my lock is as follows: Assuming that the car-door is unlocked, the employee sealing the car slipsa way-card Within the recess 9, raises the hinged cover 37, and places a seal (preferably of paper) on top of the projecting rim 36, forcing the seal over the knives 35 of the seal mutilator. The cover 37 is then shut down, which bends the edge of the seal and securely holds it, as seen in Fig. 5. The hasp 3 is then swung on its pivot 4, and as it closes the bolt 16 carried thereby is first pushed within its recess 15 and then is forced (by its spring 17) into the opening in the casing, when the hasp will be securely locked and cannot be opened with out moving the pusher 28, which would operate the seal-mutilator. Should any one attempt to unlock the car, the rack 29 on the pusher 28 would rotate the pinion 30 and the mutilator, and thus destroy the seal before it could operate the bolt 16. It is manifest that when it is desired to unlock the car the movement of the pusher would operate the bolt 16 through the medium of the bolt-operator 25. If it is desired to prevent innocent tampering with the pusher 28, an ordinary seal 40 may be secured thereto, as seen in Fig. 4.

The seal-lock herein described is most effective in operation and satisfies all the re quirements of actual service, which are by no means easy to fill, as the lock must be easily operated and unlikely to become out of order and the way-card and seal (when the latter is made of thin paper) must be well protected from rain, which is so likely to beat in.

Vhile I have illustrated the form of box which will best fill these rigid requirements, I wish it to be distinctly understood that my claims are not limited to the exact construction shown, as many changes and alterations may be made from my preferable embodiment without departing from my invention.
